Lime production line is a complete line that includes vertical preheater, rotary kiln, grate cooler, air treatment system, raw material conveyor system, finished product conveyor system, raw coal grinding system, and so on.
The limestone is heated by the 1150℃ smoke inside the kiln to about 900℃, and 30% will decompose, and the limestone is pushed by the hydraulic push rod into rotary kiln where limestone will decompose into CaO and CO2. The decomposed materials go into the cooler where they will be cooled to below 100℃ by the cold air and discharged. The discharged lime will be sent to the final product warehouse through vibrating feeder, chain conveyor, bucket elevator and belt conveyor.
